Ending an unusual period of silence on Twitter, mega-successful investment mogul Shervin Pishevar returned to the social media platform with a vengeance in February with a 21-message Tweetstorm that left many observers scratching their heads, while others pondered the deeper implications of it all.

Pishevar had a lot to say about many topics — including the stock market, the fate of Bitcoin, the plight of Silicon Valley, inflation, the economy, tech industry giants and a lot more.

For example, Shervin Pishevar seemed to predict the coming doom of Silicon Valley. He suggested its era of dominance is over. Pishevar believes that competition will increasingly come from all points on the planet because Silicon Valley has devolved into merely “an idea” rather than a geographic location.

Shervin Pishevar also thinks stocks are due for a certain downward correction. He focused specifically on the bond market, saying bonds do not have “unlimited power” to correct and stabilize the overall market. He said this tool, so often used by central banks, will lose effectiveness because it has been relied on too much.

One of the most stunning observations made by Shervin Pishevar was a prediction that giant companies that rule the business world today may soon see their influence fade. He was speaking of Apple, Microsoft, Amazon, Google and Alphabet. He dismissed them monopolies that are squelching too many small-business start-ups.

He was more positive about what he called “moonshot” operations, such as Elon Musk’s SpaceX and Virgin. He said these major players may be the “exception to the rule” in terms of major companies finding continued success and growth in coming years.

What about Bitcoin? Shervin Pishevar thinks this cryptocurrency is due for a significant downward correction, but that it might also stabilize at a price range of perhaps $2,000 to $5,000. As for these kinds of financial instruments in general, Pishevar believes they will be a boon to entrepreneurs because cryptocurrencies are “stateless” allowing much more flexibility in raising cash for new projects.

Everyone knows that Shervin Pishevar is good at making profits, but is he a genuine prophet? Time will tell.
